For all the photos taken on 15/5/1999 by William Edward Burton on trials at Incat, Joerg is right - these must be IMO 9206700 as AVEMAR (later AVEMAR L, and now ALBORAN) as the only one delivered to Buquebus that year - apparently on 31/5/1999. Owner then Los Cipreses SA, Montevideo and operated by Buquebus Espana SA, Algeciras.

Also, the camera-dated 8/4/2016 photo by "aaaa" must be AVEMAR DOS (INO 9170183) as the only one of that type operated by Buquebus Espana at that time.
